1. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

2. A nurse is reviewing the medical record of a client who was admitted for acute kidney injury. Which of the following laboratory values should the nurse expect to be elevated?

• A. Creatinine
• B. Magnesium
• C. Hemoglobin
• D. White blood cell count

Correct answer: A

Rationale: Creatinine is the correct answer. In acute kidney injury, creatinine levels are expected to be elevated due to impaired renal function. Magnesium, hemoglobin, and white blood cell count are not typically elevated in acute kidney injury. Magnesium levels may be affected in kidney disease, but elevation is not a common finding in acute kidney injury.

3. What are the signs of hypoglycemia, and how should they be managed?

• A. Sweating, trembling; administer glucose
• B. Headache, confusion; administer insulin
• C. Dizziness, fatigue; administer glucose
• D. Increased heart rate; provide a high-sugar snack

Correct answer: A

Rationale: The correct signs of hypoglycemia are sweating and trembling. These should be managed by administering glucose to raise blood sugar levels. Headache, confusion, dizziness, fatigue, or increased heart rate are not typical signs of hypoglycemia. Administering insulin in response to hypoglycemia would further lower blood sugar levels, exacerbating the condition.

4. What are the key components of a focused respiratory assessment?

• A. Inspection, Palpation, Percussion, Auscultation
• B. Observation, Percussion, Auscultation, Palpation
• C. Auscultation, Palpation, Observation, Percussion
• D. Palpation, Inspection, Auscultation, Percussion

Correct answer: A

Rationale: The correct answer is A: Inspection, Palpation, Percussion, Auscultation. A focused respiratory assessment involves inspecting the chest for any abnormalities, palpating to assess tenderness and chest expansion, percussion to evaluate underlying structures, and auscultation to listen to lung sounds. Choice B is incorrect because observation is generally part of inspection, not a separate component. Choice C is incorrect as auscultation should come before percussion in a respiratory assessment. Choice D is incorrect because inspection should precede palpation in a structured assessment.

5. A client with dementia is at risk of falling. What is the best intervention to prevent injury?

• A. Place the client in a room close to the nurses' station
• B. Use a bed exit alarm
• C. Encourage family members to stay with the client at all times
• D. Raise all four side rails

Correct answer: B

Rationale: Using a bed exit alarm is the best intervention to prevent injury in a client with dementia at risk of falling. This device alerts staff when the client attempts to leave the bed, allowing for timely assistance and reducing the risk of falls. Placing the client in a room close to the nurses' station may help with supervision but does not provide immediate alerts like a bed exit alarm. Encouraging family members to stay with the client at all times may not be feasible, and raising all four side rails can lead to restraint issues and is not recommended unless necessary for the client's safety.
